Radhika, K. R., Nalini, M. K..  2017.  Biometric Image Encryption Using DNA Sequences and Chaotic Systems. 2017 International Conference on Recent Advances in Electronics and Communication Technology (ICRAECT). :164–168.

Emerging communication technologies in distributed network systems require transfer of biometric digital images with high security. Network security is identified by the changes in system behavior which is either Dynamic or Deterministic. Performance computation is complex in dynamic system where cryptographic techniques are not highly suitable. Chaotic theory solves complex problems of nonlinear deterministic system. Several chaotic methods are combined to get hyper chaotic system for more security. Chaotic theory along with DNA sequence enhances security of biometric image encryption. Implementation proves the encrypted image is highly chaotic and resistant to various attacks.
